FAQ's About Sciatica: Causes & Preventative Measures

01-19-2018

Sciatica is a word commonly used to describe pain, numbness, tingling and symptoms of "pinched nerves in the spine" which runs down one or both of the legs. However, Sciatica is not a very specific diagnosis because it can stem from issues affecting the lower back, where pain can travel down the sciatic nerve, the largest nerve in the body, through the buttock and the back of the leg.

Top 9 Causes of Sciatica:

  1. Muscle spasm from overuse.
  2. Age-related arthritis (degenerative disc disease) either of the joints of the spine or the hip and knee.
  3. Obesity because typically patients facing weight issues tend not to move around as much which can make them more susceptible to back-related problems due to inactivity.
  4. Stress such as moving, job issues, money issues, personal life and everyday things.
  5. Pinched nerves – the real kind – from spinal stenosis to disc herniations. This can be diagnosed properly with an MRI
  6. Urinary tract infections or kidney stones.
  7. Pelvic illnesses like prostate infection or endometriosis or ovarian cysts.
  8. Vascular diseases and poor circulation.
  9. Way down the list towards the end are problems such as secondary or metastatic tumors from breast or kidney or lung or prostate.

Muscle Spasms: Most Common Cause of Sciatic Pain
Muscle spasms are the most common and also the least likely to be linked to any imaging I can perform other than a physical exam. I bring this up because many people assume that if they are experiencing severe back and leg pain they must have pinched nerves in their lower back.

This is often NOT the case, cannot be diagnosed effectively without an MRI image, and can only be roughly estimated by X-rays. In fact, after a thorough physical examination, if there are no findings of numbness, weakness, muscle atrophy, reflex changes or nerve tension signs, the likelihood of finding nerve compression within the spine on an MRI is less than 1 in 1500.

When your back and leg hurts, obviously it is of concern, but even in the most severely painful cases (without the nerve signs I just mentioned) so bad you can’t get out of bed, you can expect full recovery within a week in more than 90% of cases. People often call the symptoms of muscle-related lower back pain “sciatica” but it has mostly to do with spasms from overuse of lower back muscles, poor posture, inadequate conditioning or unusual muscular demands on the spine.

Intense Activity After Inactivity
Most patients can link their pain to a specific set of events – intense bending stooping lifting or other loads on the spine after a period of inactivity, or taking on a greater stress than is commonly experienced. Classic scenario: 4 days of golf and range practice after 6 months of no golfing. Or, cleaning out an attic of large pieces of furniture or other junk when over the previous month, the most activity experienced has been sitting at work or in the car. Other times there is actually NO explanation and NO obvious triggering events. This can be really frustrating for both doctor and patient but it isn’t that uncommon.

Do High Heels Cause Sciatica?
I’m often asked about high heels as a cause of sciatica. There’s not much good evidence written about this, but heels are associated with a lot of foot pain and eventual deformity. Flats are OK to wear especially if you are on your feet for a long time. Platforms can be a good alternative and not cause so much calf and heel tightness if worn daily. The message is, heels themselves have NOT been shown to cause sciatica from disc herniations.

Getting Back to Normal Activities After Sciatic Pain
Patients ask how to return to normal activities after experiencing sciatic pain. Assuming it is the run-of-the-mill back pain, 95% of my patients should be able to get back to daily activities within a period of 2 weeks.

What’s the easiest form of exercise and the least expensive?
A pair of sneakers and a sidewalk . Think about it – both are widely available, cheap, no special machinery necessary, available 24/7 pretty much anywhere there is dry land. It’s low impact, tolerated well even with arthritis and joint complaints, gets you out of the house and away from your computer. I recommend easing into it in ½ mile increments. Add in gentle lower back stretching, hamstring and calf stretches to pain tolerance. Make sure the sneakers fit well, have plenty of cushioning and good arch support.


A Friendly Reminder to Everyone
The best exercise is something that you can do do regularly, not just after experiencing back pain. Patients often ask, “What exercises can I do to treat this sciatic pain?” I usually respond that initially after rest and gentle stretching, and time, that regular exercise is best as a preventative measure. Three to five times a week for at least an hour of aerobic exercise, core strengthening and stretching has been documented in countless clinical trials as equally-or-more effective than physical therapy, medication, injections or chiropractic.

Get out there regularly. Like mom said, eat a good diet, don’t smoke, go to sleep early, and get plenty of exercise!
